Title: Single suture biological tissue aortic stentless valve

Abstract: A semilunar stentless valve is constructed entirely of biocompatible material, and has a plurality of leaflets that are joined to form an annulus and coapt to form a one-way valve. The leaflets open fully to minimize obstruction. A narrow rim strip overlies commissures where the leaflets join and around a base of the valve. The valve is of a conical design, flexible, easy to fit and preserves the integrity of the coronary sinuses. The valves can be implanted with a single suture row, reducing implant time significantly.
